# This pattern was tested only by listening to a Linksys WRT54G. However,

# SSDP packets should _always_ be sent to the multicast address

# 239.255.255.250, making this pattern irrelevant. (Moreover, SSDP
|
|

|
# packets should be resitricted to local networks that have plenty of
|
|
12
|
# bandwidth.) However, Microsoft, as usual, has other ideas, so maybe
|
|

|
# it could be useful. Can't hurt, anyway. :-)
